dm: device: Allow using uclass_find_device_by_seq() without OF_CONTROL

2018-12-10T05:05:32+00:00

If OF_CONTROL is not enabled and DM_SEQ_ALIAS is enabled, we must
assign an alias (requested sequence number) to devices that belongs to a
class with the DM_UC_FLAG_SEQ_ALIAS flag. Otherwise
uclass_find_device_by_seq() cannot be used to get/probe a device. In
particular i2c_get_chip_for_busnum() cannot be used.

dm: core: Export uclass_find_device_by_phandle()

2018-11-29T16:30:05+00:00

This function may be useful to code outside of the code driver-model
implementation. Export it and add a test.

dm: uclass: Add uclass_next_device_err() to return a valid device

2018-11-16T21:51:55+00:00

Similarly to uclass_first_device_err(), add uclass_next_device_err()
which returns an error if there are no next devices in that uclass.

dm: core: Allow uclass to set up a device's child after it is probed

2018-11-14T17:16:27+00:00

Some buses need to set up their child devices after they are probed.
Support a common child_post_probe() method for the uclass.

With this change, the two APIs uclass_pre_probe_device() and
uclass_post_probe_device() become symmetric.

uclass: Add dev_get_uclass_index() to get the uclass/index of a device

2018-08-21T14:21:37+00:00

This function is the reciprocal of uclass_find_device().
It will be used to print the index information in dm tree dump.

Add additional logging so that common errors when finding a device by
ofnode are easier to debug.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

dm: core: Add a function to look up a uclass by name

2018-02-03T17:08:40+00:00

Each uclass has a driver name which we can use to look up the uclass. This
is useful for logging, where the uclass ID is used as the category.

Add a function to handle this, as well as a test.
